Standard turnaround on single-building mechanical packages
Oklahoma does not let a mechanical system specialize. The same building needs full heating capacity in January, full cooling capacity in August, and equipment anchored to survive straight-line wind and tornado exposure the rest of the year.
We produce mechanical cost estimating, quantity takeoff and material takeoff for HVAC, piping, ductwork, sheet metal, process and MEP contractors across Oklahoma - priced to local labor, local code enforcement and the load and wind conditions that actually drive Oklahoma mechanical design. You get a measured takeoff, a line-item estimate, a marked-up plan set and a written list of what we assumed and excluded.

QTO
Measured quantities with no pricing applied - the option for contractors who trust their own cost database but need the counting done at volume.
MTO
Purchase-ready material lists broken out by size, material, schedule and fitting type, formatted so your supply house can quote directly from them.
HVAC
Air-side scope end to end: package units, split systems, VAV terminals, rooftop units with wind-rated curbs, exhaust fans, louvers, grilles and diffusers.
Duct
Rectangular, round and oval duct by gauge and weight, fittings, fire and smoke dampers, liner, external wrap, flexible connections and shop fabrication labor.
Pipe
Chilled water, condenser water, hot water, steam, refrigerant, compressed air, instrument air and process lines, with valves, hangers, welds and testing counted separately.

Bid
Bid-day support: scope letters, exclusions, alternates, unit pricing, vendor quote leveling and a reviewed bid summary before the due time.
Precon
Early mechanical budgets from schematic or design development drawings, updated at each milestone so the owner tracks the number instead of discovering it.
CO / VE
Independent pricing of added scope and credits, plus side-by-side cost comparison of system alternatives such as package units against split systems.
Clients
The deliverable is shaped around who has to bid with it - a mechanical contractor staffing crews, a sheet metal shop scheduling fabrication, or an energy operator checking a process number.

02 · HVAC
Air-side and equipment takeoffs for new construction, replacement and retrofit, from one package unit to a district plant.
03 · SHOP
Duct takeoffs by weight and gauge that convert directly into fabrication hours, with fitting counts your shop can schedule.
04 · PIPE
Energy-sector and industrial piping with weld counts, material specs, testing and insulation carried as separate lines.
05 · MEP
One coordinated estimate across all three trades, priced on a single consistent set of assumptions.
06 · GC
Independent mechanical budgets for checking subcontractor pricing or carrying a number when coverage is thin.
07 · ENERGY
Mechanical and process cost checks for facility upgrades, turnarounds and utility distribution projects.
08 · OWNER
Third-party cost review on equipment replacement programs, capital plans and multi-site portfolios.
What contractors say
“They priced the wind-rated curbs correctly the first time, which is more than I can say for the last two estimators we tried.”
“We bid a lot of energy-corridor process work, and they know where the mechanical scope stops and the process scope starts. That saved a lot of back-and-forth.”
“Nobody else scheduled the balancing to actually check both heating and cooling. That single note saved us a callback.”

How It Runs
Six steps from the drawings in your inbox to a package you can walk into bid day with.
1
Mechanical drawings, specifications, addenda and the bid date. A PDF set is enough. Tell us which scopes are yours and which belong to another trade.
2
A mechanical estimator reviews sheet count and complexity and returns a fixed fee and a delivery date, usually within a few hours.
3
Digital measurement in Bluebeam, PlanSwift or AutoBid, colour-coded by system so nothing is counted twice and nothing is missed.
4
Material from current supplier data and your preferred vendors; labor built from standard units adjusted to your crew productivity and the Oklahoma region you work in.
5
A different estimator reconciles quantities against the equipment and air device schedules and confirms wind and freeze-protection scope against the specification.
6
Full package plus a walkthrough call. We stay reachable through your bid date for addenda revisions and last-minute questions.

The Oklahoma Design Problem
A Wisconsin estimate is built around heating. An Alabama estimate is built around cooling and humidity. Oklahoma will not let you pick a side. Summer design conditions run genuinely hot and humid, winter design conditions bring fast-moving arctic fronts and real cold, and the same building has to be sized for both without either system riding on the other's coattails.
Layer severe convective weather on top of that. Oklahoma carries some of the highest design wind speeds in the country, which reaches directly into mechanical scope: rooftop units, condensing units and exhaust equipment all need wind-rated curbs, tie-downs and screening that a calmer climate would not specify. February's hard freezes are a live risk to exposed piping and equipment that a mild-winter state does not plan around.
An estimate that assumes one load dominates, or that treats wind anchoring as incidental hardware, will undercount an Oklahoma mechanical package in ways that show up at startup, not at bid time.
01 - Full-size heating and cooling
Both plants sized to their own design condition, not derated against each other.
02 - Wind-rated equipment attachment
Curb anchoring, tie-downs, screening and structural coordination for rooftop and pad-mounted equipment.
03 - Freeze protection
Heat trace, insulation and drain-down provisions for exposed piping and outdoor equipment.
04 - Dust and grit filtration
Higher-capacity filtration and more frequent service access built into red-dirt-region air handling.
05 - Storm-hardened controls
Surge protection and backup power coordination for critical mechanical systems.
06 - Dual-season commissioning
Balancing scheduled to actually verify both heating and cooling performance, not just whichever season the schedule lands in.
Where Oklahoma Bids Go Wrong
These are the items we see missed most often when reviewing a contractor's own Oklahoma takeoff. Each one is a standing check before an estimate leaves our office.
01
A standard curb is priced where a wind-rated curb with additional anchor points was actually specified or required.
02
Rooftop equipment screening adds real wind load and structural coordination that a mechanical-only takeoff misses.
03
Refrigerant and condensate lines routed across an exposed roof without the heat trace or insulation the winter design condition calls for.
04
Hospitals, data rooms and process facilities need mechanical systems coordinated with emergency power, priced as its own scope.
05
Balancing scheduled once, in whichever season construction happens to finish, instead of verifying both heating and cooling performance.
06
Standard filter banks specified where higher-capacity or more frequent-service filtration was actually intended for the region.
07
On energy-sector work, where mechanical scope ends and process/instrumentation scope begins is assumed rather than confirmed against the P&ID.
08
Permit and inspection timelines assumed uniform statewide, when adoption and review speed actually vary by city under Oklahoma's code framework.
Three Markets, One State
Labor availability and project mix change substantially depending on where in the state the work sits.
Oklahoma City
Tulsa
Norman
Lawton
Stillwater
OKC, Norman, Edmond, Moore, Midwest City
The state's deepest commercial, healthcare and government market, anchored by state government facilities, two major medical centers and university work in Norman. A mature subcontractor base and the state's largest concentration of institutional projects.
Watch: Phasing on occupied campuses, state procurement requirements
Tulsa, Broken Arrow, Owasso, Bartlesville, Cushing
Historic oil capital with a concentrated midstream and refining industry, centered on the Cushing crude storage hub. Process piping, tank farm mechanical scope and industrial utility work are a steady share of the mechanical market here in a way they are not elsewhere in the state.
Watch: Process scope boundaries, plant shutdown windows, specialized welding certs
Lawton, Duncan, southwest Oklahoma
A military-adjacent market with base-related construction and support facilities alongside conventional commercial and agricultural work. Federal and military work brings its own wage determinations and security requirements distinct from private commercial projects nearby.
Watch: Federal wage determinations, base access and security clearance timing
Stillwater, Enid, Ardmore, Ponca City, McAlester
Agricultural processing, regional healthcare, university work at Stillwater, and smaller industrial and energy-adjacent facilities spread across a wide geography. Crew travel and material freight are real cost items that a metro-based estimate will underprice.
Watch: Crew travel time, freight, subcontractor availability
We work remotely and deliver statewide, across all 77 Oklahoma counties. These are the markets we estimate in most often.
Bidding somewhere not listed? Send the drawings anyway - coverage is statewide, including rural counties where crew travel and freight need to be priced in.
Regulatory Context
Statewide adoption, local enforcement · Construction Industries Board licensing · wind anchoring · energy code · open shop and prevailing wage · storm shelter ventilation
OK-01
Oklahoma adopts its commercial building and mechanical codes through the Oklahoma Uniform Building Code Commission, but local jurisdictions handle plan review, permitting and inspection. Adoption timing and local amendments can differ between Oklahoma City, Tulsa and smaller cities, so we confirm the governing jurisdiction before pricing permits and general conditions.
OK-02
Mechanical contractors are licensed through the Oklahoma Construction Industries Board, with classification requirements separate from general contractor licensing. Which portions of a scope a given license covers affects who can legally hold that part of the bid.
OK-03
Structural provisions for wind design directly affect mechanical scope - rooftop equipment anchoring, curb detailing, screening and, in some jurisdictions, additional bracing requirements. These are cost items in the mechanical estimate, not separate structural line items to ignore.
OK-04
The adopted energy code sets minimum equipment efficiency, duct and pipe insulation, and economizer requirements. On replacement work this regularly forces a higher-efficiency unit than the one coming out, changing equipment and connection cost.
OK-05
Oklahoma is predominantly open shop, and private commercial labor is priced from crew composition rather than a negotiated agreement. Qualifying public works trigger Oklahoma prevailing wage requirements, which change the labor column against comparable private work of the same size.
OK-06
Some jurisdictions and building types carry storm shelter or safe room requirements that intersect with mechanical scope for ventilation and life-safety systems in shelter spaces, particularly on schools and public buildings.
Regulatory notes are provided for planning context. Adopted code editions, jurisdictional authority, licensing rules and thresholds change over time - confirm current requirements with the authority having jurisdiction and the engineer of record.
